DielectricShape Block

DielectricShape:

Works with VSimEM license.

This block is required when using a multiDielectricUpdater. The block sets the permittivity to a specified GridBoundary.

DielectricShape Parameters

gridBoundary (required string)

The name of the GridBoundary to which to set the permittivity to.

relPermittivity (optional float, default = 1.0)

The value of the permittivity within the specified gridBoundary.

isFlipped (optional int, default = true)

Whether the gridBoundary interior is flipped.

conductivity (optional float, default = 0)

Specifies the conductivity of the dielectric for cases that implicitCylEmUpdater is used as the field updater. If conductivity is specified, then electricField must also be specified in the implicitCylEmUpdater block.

DielectricShape Example

<FieldUpdater setInvEps>
  kind = multiDielectricUpdater
  lowerBounds = [0  0  0]
  upperBounds = [46  51  51]
  permittivityField = invEps

  <DielectricShape cylinder0Unionsphere0Shape>
    gridBoundary = cylinder0Unionsphere0
    relPermittivity = 9.9
  </DielectricShape>

  <DielectricShape cube0Minuscylinder00Shape>
    gridBoundary = cube0Minuscylinder00
    relPermittivity = 9.0
  </DielectricShape>

  backgroundPermittivity = 1.0
</FieldUpdater>
